Ancient sand dunes exposed off a cliff face on the shoreline of Nova Scotia at Island provincial park. The juxtaposition of the high angled stata and flat lying layers above revels the drastic change in climate in Nova Scotia's history; from vast sand dunes to a calm lake system, and presently the western coastline of the Atlantic Ocean.

This clay wall is one of the most peculiar features of the living landscape of the badlands of Civita di Bagnoregio (Italy). In the last century a road was located on this clay wall and still some wood structural elements are visible. In the picture background, there is a country house, when will be the time for relocation?

In 1877 the USGS published a report "On the Geology of the Henry Mountains", on the small range of peaks in southern Utah. Up to that point, little scientific study had been made of the unassuming peaks, but the author of the report, one Grove Karl Gilbert, not only detailed the structure and mineralogy of the landscape, but in doing so also laid the foundations for much of modern geomorphology.
While beautiful, the range is isolated and of limited economic value; Gilbert himself notably wrote that "No one but a geologist will ever profitably seek out the Henry Mountains", while the name given to the range by the Navajo is Dził Bizhiʼ Ádiní, literally meaning “mountain whose name is missing”. And yet, the wildness of the range is sufficient attraction for some - this is Mt Hilliers, at the centre of the 5 peak range.

Storm fronts arrive on Britain's west coast in waves throughout the winter (and very often the summer too!) It is not unusual to see rain falling on a beach with hail and snow lying, whilst a rainbow pierces the clouds.

This wonderful mature thunderstorm cell was observed near the German Aerospace Center (DLR) Oberpfaffenhofen. A distinct anvil can be seen in the background meanwhile a new storm cell is growing in the foreground of the cumulonimbus structure. Mature storm cells like this are common in Southern Germany during the summer season. Strong heat, enough moisture, and a labile straitification of the atmosphere enables the development of this exciting weather phenomenon.

The surrealistic geological formation of the Love Valley, nearby Goreme in Cappadocia is result of the natural forces during the intense volcanic activity.
The formation of the so-called "fairy chimneys" started during the third geological period, when three volcanoes located on the edges of this region began erupting frequently. The deposits of volcanoes ash, lava and basalt laid the foundations for today's landscape. Earthquakes and ongoing effects of erosion have contributed to form the valleys and the "fairy chimneys" that can be seen today.

The coastline of the Gower Peninsula presents dramatic and visible evidence of climate change - marking the southern limit of the Last Glacial Maximum, till plasters limestone, in parts forming solifluction terraces. The coastline is dotted with caves that are rich in Quaternary flora and fauna, including the famous Red Lady of Paviland, the oldest known ceremonial burial in Western Europe. Worms Head (pictured) is the most spectacular remnant of a peneplain in the region. The shipwrecked Helvetica shipwreck (1887) is now permanently buried in the beach.

Coraholmen Island doubled in size when the Sefströmbreen glacier overrode it during its surge. A range of landforms were deposited holding clues to the past dynamics of this Arctic surging glacier. The photo was taken during a field cruise as part of the UNIS AG-350 Arctic Glaciers and Landscapes course in Svalbard.

In 2015 a wildfire burned 5000 hectares in size of the Maligne Valley area of the Jasper National Park, Canada. One year later, I took this photo at the Medicine Lake. On the right side you can see the burnt forest, where the fire came to stop. The contrast between the charred black versus the vibrant green versus the singed red tells a powerful story about forest resiliency and renewal.

In the Middle of the Apennines lays the Gran Sasso Mountain.
since Mesozoic rifting stage sevarl compressional and extensional events occured leading to the subduction of the African plate beneath Eurasia and driving the Apeninne orogeny. The result of this rising generated the appenine mountain chain which summit is visible in this photo during a fleeble pinkish sunset that enlight the summit of mountain.

The grassy Namibian desert is pock-marked with millions of circular patches of bare earth
just like these shown in the picture between linear dunes . Viewed from a balloon, they
make the ground look like a moonscape. Commonly known as fairy circles, the patches
range from 2 to 12 metres across and appear in a 2000 kilometre strip that stretches from Angola to South Africa.
For many decades, the fairy circles extending uniformly over vast areas in the landscape, have puzzled laymen and scientists alike. They are subject to a lively debate and contrary hypotheses on their origin exist. Some researchers claim fairy circles were caused by termites, others propose they are the result of vegetation self-organization.

Climate scientists processing ice core samples in the EastGRIP science trench 10 m under the surface of the Greenland ice cap. The new trenches of the EastGRIP ice core camp require minimum building materials utilising giant inflatable balloons that are dug in and covered with snow. The latter is left to sinter for a few days, thereafter leaving back an arch-shaped underground trench ideal for ice core processing activities.

This picture was taken in Myvatn geothermal area. Seeing the steam vent of geothermal in this area while the temperature was -22 degree Celsius is the best experience in Myvatn. The difference of ambient temperature and the heat temperature from inside the Earth is really stunning event to see.
Iceland is situated in the middle of two tectonic plates (Eurasian and North America tectonic plates) that give more than hundred active and inactive volcanoes in this country. High activity of volcano and the depth of the magma, which is near the surface, triggers the high production of geothermal in Iceland. You can easily find other thermal bath in the southern and northern Iceland, besides Blue Lagoon. In addition, Icelandic use geothermal source as the main source of space and water heating and occupied more than 10% for electricity source. During winter, almost 100% space and water heating comes from geothermal energy and almost all the main roads in Reykjavik are feed by this energy source. Because of that, Iceland is well-known as the world leading green and sustainable country in the world.
How geothermal energy can be produce? For the space and water heater source, the power plant uses the pipe called heat exchanger to convert the hot water inside the earth into the heat. It is then distributed within the steam pipe to the residential area. For the electricity source, the power plant captures the steam or hot water from the geothermal area to drive the electricity generator, which convert the heat into electricity. The power plant then distributes the electricity to the residential area. In short, the geothermal plant is able to produce both heat and electricity.
